Primary finding
Probable cause
The pilot’s failure to maintain directional control in variable wind conditions.
Investigator assessment
Analysis narrative
The pilot of the tailwheel-equipped airplane reported that, during touchdown, the airplane "weathervaned to the left and full right rudder could not keep it on the runway." Subsequently, the main landing gear dug into the soft mud, and the airplane nosed over. The airplane sustained substantial damage to the empennage. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation. The automated weather observation system located on the accident airport reported that, about the time of the accident, the wind was variable at 6 knots. The pilot landed on runway 34.
